One of my SE/30s came with a security lug fitted. It offended me , but a couple of strokes with a new hacksaw blade showed that it had been designed to be un-removeable without doing severe damage to the Mac's case. The only feasible path is to cut the plastic tabs off inside the case bucket, which at least leaves no trace of the operation on the outside.
The surgery on the chassis needed to install the accelerator will make some of your fellow-soldiers blench, but it is your call on your machine. 003, who hasn't posted here for quite a while, installed an HDD vertically beside the PSU of his SE/30. I half-remember some discussion about the matter before The Fall, but that is presumably disembodied in the ether now. 003 also was exploring the use of a flexible magnetic/radiation screening to shield the drive, but heat dissipation from the swaddled drive would have to be ensured. My own belief is that keeping the HDD's circuit-board on the side remote from the CRT should be adequate, but I haven't tested that belief in practice.
As for your specific questions, yes, it should be possible to ignore the FPU on the logic board. It will be a pain to remove. Neither of two CPU-socketted SE/30 boards that I have (rev. A and rev.10) has a socketted 68882, nor has the IIci for which the DayStar cards are drop-in replacements into the PDS slot. Rather than overclock a 33MHz CPU on the card (2x), why not consider a 50MHz (3x) PowerCache card?
This link, which raises the matter of PDS slot addresses that you will have to attend when there are multiple cards, may give you some food for thought also about internal physical configuration:

Given ethernet and SCSI, I should be strongly inclined to dispense with the FDD entirely, and attach the HDD cradle directly to the chassis floor.
