I have a kit I call the "PdwP Crush"....it's all shades of blues..I wanted to try out some of the dw performance series and PDP platinum series and a Crush 13" tom....so I said what the hell, and bought them...added a PDP blue fade kick...it's a mish mash, but it looks "unique" and boy does it sound great!
So, my opinion, for what it is worth, of your mixed kit is "fine by me"; especially if there are good stories behind the acquisition or history of the individual drums....and of course you could have a lot of fun at a gig after a few beers and tell good stories..."why that 22" deep gretsch kick was on the titanic, son!" LOL
I think if you are asked to back up a solo artist or act in a sideman type of role, well, you probably won't be using that kit
thats my $0.07
