Could you make GOG installer for included DOS version? Blood Fresh Supply has it's original version One Unit Whole Blood in GOG installer version included, could you do the same with Strife?

If you’re not keen on setting up DosBox to play the classic version, a really good alternative would be to download Crispy Strife, an accurate port of the Dos version that runs well on modern machines.

Just download it from here (https://github.com/fabiangreffrath/crispy-doom/releases/tag/crispy-doom-6.0) and then add STRIFE1.WAD and VOICES.WAD from the classic Dos version to start playing.

Thank you for information, but I was thinking about completing the collection of GOG-installers of different versions of games, like Blood, Rise of the Triad (original and ludicrous edition), Doom (original and enhanced), Quake (original and enhanced), Doom 3 (original and BFG edition). It would be nice to have Strife original and veteran edition in the same format too.

No worries, and I totally agree. Seems a bit out-of-character for GOG to include just a .zip file with the DOS version in it.
