Possibly, though you can usually order "universal" rails to fit
tapped-hole racks. It's a hassle, and usually an unaccounted expense.
And IME these rails aren't nearly as nice on your hands and sanity as the
snap-in rails most server mfrs ship standard.

I'd suggest getting an actual cabinet that you can order unassembled.
I'm thinking specifically of the excellent CPI Megaframe cabinets. The
only parts that don't knock down are the bases, tops, doors and sides -
and you can carry those easily through the door. The uprights and braces
are extruded aluminum, and then your actual mounting rails (in square
hole, round punched, tapped threads, or any combination) are steel, bolted
inside of those.
When we closed one datacenter and found we had to scrap 40 of these things
(!!!) I took apart four and they all fit inside my normal-sized car. They
were very easy to then carry down the winding narrow staircase to my
If you're very tight on space inside the room, you can get different door
options, or just omit them entirely. This changes your thermal and
acoustical management, but I'm guessing you already have some challenges
there, if your door is any indication.
These CPI cabinets are not cheap, but they are very nice, can be carried
through tight/low doorways in lightweight sections, and have considerable
load ratings. 2000 pounds I think.
All that said, I have removed and disassembled door frames, ceilings,
walls, whatever to deal with whatever issues where we couldn't take racks
apart or otherwise spend our way through it. This doesn't work so well
when you have concrete walls, welded doorframes, or unforgiving landlords.
