Default Should I move my MLT Output to the bottom?

I have a 50-quart "cube" stye MLT that did not come with a spigot, so I drilled a hole where it /should/ have been (based on a dip on the inside surface) and stuck my CPVC in with liberal use of PTFE tape, a homemade PET washer on the inside and a thick coating of JB Weld on the outside. I use a mesh hose made from aluminum screen rolled up and held with aluminum cable ties (holds up very nicely and is pretty much disposable, since it costs $0.50 to make a new one).

Now, my question is... I'm suffering from a massive amount of dead space; Wouldn't it be better to cover that hole and redo it so that my output hole is on the bottom? That could seriously kill any and all dead space, especially if I just cover the hole with, like, a balloon of overlapped aluminum screen (imagine a turkey baster bulb sticking out of a kitchen sink drain, only made of screen mesh). I'm sure a different shape would make stirring safer (for the mesh), but I don't know what shape I could make with this stuff.

I'm fairly certain that a false bottom, while it would be the best answer, is pretty much abhorently difficult to put into one of these. Maybe a mesh tray of some sort, screwed to the walls? I tried that for a planter once, and it worked, but eventually gave out and one side ripped out (the screen, not the screws). I'm just rambling at this point, someone take it from here!

If you can I think bottom drains are great. I converted my boil kettle to have a bottom drain and now I don't have any deadspace there and I can even squeeze the hops with a sanitized spoon to get out the last of the wort from them (important with huge IPAs). It is an electric kettle though so I don't have to worry about protecting it from flame. As far as a MLT I think it could work rather well depending on how it is constructed. If you are still going to use a braid you'll have to figure out how to transition from vertical to horizontal, but you won't have to worry about siphon issues anymore.
