...has no one made an EFI bootloader that will start BIOS operating systems?
Hackintosh users have been doing the reverse for ages, because Macs have used a variation of EFI since they first switched to Intel, long before EFI existed on PC.

I'm not having much luck finding very much information on it though
For the purposes of running Windows 7 on modern systems, we'd have to do the reverse, emulate a legacy BIOS environment from a UEFI system. XOM appears to fit this description, it simulates a legacy IBM BIOS on an Mac's EFI boot environment.
I only briefly Googled it earlier, but thanks for the ideas, rest assured, if I ever look into it and get Windows 7 running, I'll post about it.
Of course this won't fix your driver problems, if any.
Alternatively load and execute a CSM in your UEFI firmware, but we do not have a reference implementation of that and AMI, Phoenix do not want to share.
I'd still have the problems of no drivers, but it's a step closer...
But I'm pretty sure you can't do the reverse with Clover specifically. It's designed for booting macOS, which always uses EFI.
