Any 10mm can be converted to 40 S&W by having a new barrel fit and a little tuning by a competent smith. The question is, why would you want to?
The 10mm OAL works well in the 1911 platform whereas the shorter cartridge OAL of 40 S&W require mags with a spacer and sometimes have feeding issues.
About 12 years ago now a friend worked at a department that only allowed 40 S&W guns so he had Nighthawk build him a 40 S&W GRP. It worked, but shooting it side by side with a 45 ACP gun left me always going "meh."
To me the 40 S&W 1911 is more a novelty than a practical alternative.
Now the 38 Super loaded to its potential is a whole other matter...
