No problem, man!
Oh, and here's my first entry, an easy to do Imperial that would look less recognizable with only a little work:
Head: Evo gray clone commander?
Gun: Jango Fett
Cane: Tion Medon
Everything Else: Veers
Back Story:
K, the way I figure it, I don't read the comics, I don't read the books. SO, if this has already been thought of, or if it flies in the face of what is 'possible,' so be it. It's just an exercise in creativity

As the battle of Geonosis began to fade, a commando surveyed the arena's destruction. Out side of danger, he removed his helmet and looked upon the once-beautiful architecture with his own eyes. Something approaching joy filled his thoughts. A battle had been won. And it was good.
Now came the easy part, picking up the pieces. He would not stay for long. He knew he would be needed in another theater of this new war, and soon. But for now, he watched the bodies being moved for disposal or transport. He watched the Jedi recovering the remains of their brothers & sisters.
As he scaned the immediate area, a glint of the morning's soft orange light on polished metal captured his attention. Investigating, the commando unearthed one of Jango's fallen & discarded guns with his foot. Removing his gloves, he picked it up, moved it back & forth. He he felt it's weight in his hands, and let the rising sun reflect into his eyes again, and again.
New, unexpected thoughts wound their way into sections of the clone soldier's fortified barracks of a mind. This had not been part of training. These feelings had not been part of his 2 yr existence, in which all that was supposed to be necessary for life had been flash-pumped into every molecule of his being. RC-421 looked out over the battle ground again. A battle had been won. And it was good. An enemy decapitated - in more than just the physical sense. And this too was good. But a father had been destroyed, made unsalvageable. And this was good? The answer was in his head without him having to think it.
Yes, his father had been an enemy, that much had been made unavoidably clear. Free thought on this subject was at odds with the objective. But a young brother had been taken away... No orders had been issued regarding this small one. And this, was this good?
Time Passes...
Somewhere along the line, certain clones of Jango Fett DID find the 'cure' for their short life spans. BUT, like all good paranoid dictators who overthrow democracy (because they think they know what's right for their
wallets people) Palpitine ordered all the commander, ARC & commando clones destroyed soon after Order 66 was 'completed.' (Read your history - it's what happens.) Like the victims of the Jedi purge before them, some survived and went into hiding. There, in exile, some found ways to produce offspring. Tho' most of the children of the genetically despoiled clones died within the first few years of life, some were 'lucky' enough to live a full life of sorts, but with various genetic defects taking their toll. Their children, in turn, will find life difficult too, but easier than that of the past two generations. And they will be strong enough to avenge the destruction of their heritage.
This is one of the new breed of Mandalor. He takes his place in a seat of power in the new Empire; two generations removed from the time of the murderous betrayal of Palpatine. And though his forefathers had, at one time, comprised the entirety of the Grand Army of the Republic. No one knows his history. You see, history is writen by the winners. And there has been no winning side for almost a century. No one can place the appearance he has inherited from his now dead family. No one remembers the faces of his grandfathers.
Oooh, srry - that was a bit long - someone let me know if I need to keep it shorter...
