I play baritone ukulele tuned dgbe similar to a guitar, could I take an acoustic bass guitar and use classical guitar dgbe strings on it to turn it into a big baritone ukulele?

Technically, if you have the right string gauge.  You would need to find a piccolo bass set, maybe Rotosound still make them, and tune it to the top four strings of a guitar.  But you'd probably find there was a bit of adjustment in terms of string tension and playing technique for the lower register, especially chords.  You might even decide you just don't like the basic character of the plucked note.  Piccolo basses tend to be quite twangy.
