Dude, do whatever you want and just be happy with it.
I totally understand why you are doing this. It's not like you are wanting just a plain-Jane drum set. You are wanting some that looks good, right? Some of those wood veneers and finishes come at a remarkable markup. I see kits all of the time on the BumWrap with all kinds of wood finishes.
There are a couple of reasons NOT to go with Bumwrap though:
1. Sometimes it's easy to see where the scan "starts over" in the wood grain. It's really hard to explain. Look at the tops of the kicks in this picture. See how it sort of mirrors the other side? Veneers aren't supposed to do this on drums:
Depending on where the seam is on the wrap, this may be your only choice is to wrap it like this. I guess you could ask them to "off-center" the grain for you, which probably what I would do.
2. The "wood grain" print will not be the same size from drum to drum. In other words, the bigger the drum, the bigger the grain or graphic. They do not compensate the graphic for bigger and/or smaller drums. Like if you had a stack of actual wood veneer you were going to use to wrap your drums, you would cut it all from the same stack. The grain would be consistent. However, Bumwrap's grain patterns will vary in size depending on the drum. While this may be great if you are getting flames or bubbles or whatever, if you are really anal about such things, maybe Bumwrap isn't for you. Maybe they compensate for this now, but you may have to request it. While you can see it in the pic above, you can really see the grain variation in this pic:
If neither of these will bother you, I'd say go for it. You will save a boatload of money, and the wrap (if done properly) will not harm the finish under it.
