Looking to vault my ceilings, could really use some input.

sorry about the massive pic!

Well the drums are bound to sound thin because they are just black heads with no shells......:-)

I always welcome high ceilings.

For recording drums in restricted space I recommend using PZM's for the overheads. I have had good results placing them on the wall behind the drummer. The ceiling is good too. Any mic can be used as a PZM by simply placing it on the boundary, perhaps on foam to prevent structure borne vibration. DPA4061's are superb at this job.
With PZM's there is no destructive comb filtering from the boundary they are on. A very clear open sound with full spectrum LF.

Do whatever you can to raise the ceiling and kill the reflections. They will cause you do much pain with boxy drums..... You'll wish you had.
A u 67 into a 1073 in a boxy room sounds boxy and bad.
A u67 into a 1073 in a nice room sounds, well, nice.
