Yep, it works fine to get you there. I made the mistake of wearing my blue armour in (should have put it on once I'd rocket jumped there). I also got caught up on a captain a couple of times, costing me a move and a bit of health/armour. But 3 rocket jumps and you're there (with a bit less health than you started with of course. Quite a bit less. Maybe mix and match? Run at the start, two jumps perhaps?).
Because you've been specifically mentioning a technician, I made up a quick save with a technician for you to practice with. As requested, it's totally build un-specific. Well, it could probably fire a pistol a bit, but I haven't used a pistol since the first 3-4 formers I killed in level 1. I have taken the liberty to drop your technical mod onto your original shotgun. It just made the run really easy up to that point (plus I got plenty lucky, not many knights, etc).
It's about as easy as I could make it. You've got a tech modded shotty, a RL, 2 chainguns, heaps of armour, stacks of medikits and plenty of ammo. And some powercells, for no real reason. You've also got 170% health due to a supercharge on the previous level. I really shouldn't have grabbed it, but you'll have enough bullet soak to REALLY test things out on what works and what doesn't.
The build was WK->WK->SoaG->SoaG->DG. So absolutely no help from the build for you. And a really nice set of boots or armour after you nail the level. Or nice pistols. Whatever you want.
I was really damn lucky, I got all this crap on my second try. By all means, if you have a pet hate of save-scumming, you're not obligated to use it. But it's a re-useable one, with all kinds of things to try, no build advantage, and a big health buffer (which I shouldn't have included. It sort of nullifies half the point of a test save). Just remove everything in the filename after the word "save", copy it to your DoomRL directory, and you're good to go.
BTW, Rocket jumping does work to get you to the AM. It doesn't work well though. You'll see just how much life it'll cost you. But it does get you there.
Anyway, here it is:
