Here's a hoopy one,
build a kit, any kit, either from the box , whif or revive an old model then let your spouse/partner/significant other/soul buddy/BFF/close friend/folks next door/complete stranger in street, design/dictate the colour scheme.
Too radical?
I realise if you are going through a bad patch or your designer is in a mischievous mood you may be opening yourself up to a whole lota of hurt ! ( or a very unique challange)
