I had thought of using a barrel liner and cylinder sleeves to convert one into a .17HM2, however, that being said, it would have a host of outrageous PSI/CUP's put on the gun, latch, cylinder, etc. So, still dreaming, I see that for hilti guns, and other powder actuated nail guns, a .27 caliber rimfire "blank" is used, BUT, there are also some .25 caliber rimfire blanks made.
I suspect you would run afoul of the antiquity rules in manufacturing a modern 25 RF. AFAIR the rules state "manufacture before" or "ammunition no longer available", but it would be interesting to see the response of the firearms bureaucracy.

.25ACP would not do, it falls under prohibited, as would any adaptation to turn any antique into shooting any caliber listed in the antique regs as a no-no.
Antique Handguns:
* manufactured before 1898 that can discharge only rim-fire cartridges, other than 22 Calibre Short, 22 Calibre Long or 22 Calibre Long Rifle cartridges;
* manufactured before 1898 that can discharge centre-fire cartridges, other than a handgun designed or adapted to discharge 32 Short Colt, 32 Long Colt, 32 Smith and Wesson, 32 Smith and Wesson Long, 32-20 Winchester, 38 Smith and Wesson; 38 Short Colt, 38 Long Colt, 38-40 Winchester, 44-40 Winchester, or 45 Colt cartridges
