Then can you emulate a 6507 cycle-accurately on a surface mount board that fits within the package envelope of an original 6507 DIP-28?

That exists but for 6502. The 6507 was not used on arcade boards, just for the 2600 home console. (Of course it could be easily modified to be used as a 6507)

This is a link to some emulated 6502 cycle accurate units both using ARM or FPGA

The 6507 is just a cut-down 6502 without all the address pins broken out. You could fit a 40-pin chip on an adaptor board hovering above the PCB on an Atari 2600, for example.

You may need to do some Grievous Bodily Metalwork to make the screening can fit.
