We see HEV zombies in Xen but they were probably for a long time there. Shouldn't they evolve into Opposing force Gonomes?

They already said many times years before Xen was released, there won't be any Gonomes. This isn't opposing force. This game is more setting up for Half-life 2 canon rather than gearbox's canon. Antlions would've made more sense.

BS, we got Medics in HECU squads. Yeah.

I never said there weren't medics

Chances are any question of "Why didn't we get...?" can either be answered by one, some, or all the following:
1) Valve rejected it. Remember copyrights can affect what's allowed or not allowed. If Valve says no, Crowbar had no choice but to obey.

2) Crowbar found it didn't work for the context of Black Mesa. Remember the Leeches from Half-Life 1? Crowbar cut them from Black Mesa finding they didn't work for Black Mesa.

3) Any wanted content may have the potential be modded in though with no source code access, modders would have a hard time coding anything new. Remember Crowbar has ceased development on Black Mesa and are working on a new game in a new IP.

You asked the same thing on Opposing Force forums so i will give you the same answer that i gave you there. Black Mesa isn't a direct remake, it is a fan reimagining
