Use straight VARIABLE instead of Z80MEM+. Initially, I used this system to allow z80a to be embedded in a system binary, but now I don't think it's worth it. Compiled, z80a is 2.5k. Sure, it's a sizeable amount of RAM, but I think that even with it in RAM, I'll manage a bootstrap within my most constrained machine, the SMS with 8K.
