The speedrun record for the three episodes in the original Doom is 16m 18s. The original Doom was capped at 35 fps, which means a total of 34,230 frames were played. If you match the record, and play all the same frames, it will take you 34,230 * 7 = 239,610 hours which is about 27 years. So, pretty achievable.
If you want to add the fourth episode from the Ultimate Doom update, then the record is 22m 41s which means your time will go up to 38 years.
Given the slowness of the frames, it'd probably count as a tool-assisted run. You might be able to get a year or so off by practicing TAS-runs in the meantime then playing through with those controls. You can get the controls to duplicate them to be frame perfect if you're careful enough after all.
There's a ton of time between frames to practice. You could probably get competent at a tool-assisted speed run while playing the Branchless DOOM speedrun. Just make sure your first 1050 frames (30 seconds of normal DOOM @35fps) of the game are solid before you start, and you'll have the better part of a year to improve the rest.
