Kitty thinks you number one.

When doing that type of profiling , you could use plywood for your base plate or between your aluminum base plate and part since you aren't worried about the Z axis being all that critical. Then bolt it down using holes you have put in part or hold down clamps.
Use several so you can move them out of the way of the cutter as it advances then put them back as needed.
