Ordinarily, DOS takes 9D00-BFFF, and HIMEM is set to 9600.
With "HIDOS" (e.g., DOS-UP), HIMEM is set to BEAF or thereabouts.
If an image of INTBASIC (just E000-F7FF - so not Programmer's Aid) were
relocated to A000.B7FF, possibly with tweaks to the HIDOS image to make it
"smart" to the relocated INTBASIC, and reserve the memory. The result
would have HIMEM at A000 - still higher than 48K DOS. Perhaps DOS could
even be reworked further: it could straddle D000-DFFF on both pages, then
have a little spill down into low memory, and you could have HIMEM at BC00
or thereabouts with both FPBASIC and INTBASIC available...
