I love how stylized this model is! Have you considered a potential HL2/GMod port? I know I and many others would love to use this as a player model in those games too!
to install the mods drop the contents into the "valve" folder (or alternatively, create a folder called "valve_addon" and put the contents into it.) if youre going to play multiplayer. the people youre playing with will need to have the model installed too.
Half-Life was built with mods in mind, just open the game folder (you can right-click on the game in Steam library and press "Browse local files") & unpack the contents of the archive ("models" folder) into "valve" for HL1 or "svencoop_addon" for SC and select playermodel from Options -> Multiplayer
you can use the _addon system for half life as well. to keep your directories clean. (so that would be just creating a folder called valve_addon and the game will pick it up)

it'd be nice if it was possible to see it on the hl2 workshop somehow

any plans to release the model on its own or port it to gmod/vrchat or something?
