Interesting question. I guess with today's processing power you could have a much more expensive offline preprocessing step and create a much better BSP tree, reducing the impact in runtime? I don't think linedefs take that much memory, but you could hit the limitation of number of textures in the same level, since I doubt 90's Doom did streaming from disk. So you probably can get massive geometry but a relatively homogeneous-looking level.
