How about a castle theme since your so into Rampart, that would be cool, like paint your cabinet grey brick and put the rampart knight on the side or something. Call it Castle Avrus Arcade
I was thinking along the same lines, except I think you could kick it up a notch
and make REAL castle ramparts along the top of the cab, then paint the
whole thing in a castle-wall motif. Your side art could be shields, family
crests, swords, that sort of thing. You could even hang banners or flags or
have a crown in the marquee.
I don't think making real castle ramparts is too big of a challenge from a
standard upright cab... just extend the side panels a bit and maybe attach
a front rampart piece via L-brackets to the top. If you wanted to get
fancier you could build extensions like towers that could hold your speakers
and such, but that depends on how much work you want to do.
Geez, I'm talking MYSELF into this idea... and the funny thing is,
I just added Transformers side art to my cab!
