Problem with the Dorian "tonal system" is that the V is minor (a in d dorian). Similar problems exist with Phrygian, Lydian...usw. If you "fix the Dorian V" to work as a V would in a major key (A dom 7 cadencing to D minor...or major), it turns out to be the same as the Aeolian mode (or the "minor system" we still use today).
Composers from the church polyphony days had to constantly tweak the modes to make them work (eg., using C# to cadence in Dorian...well, C# doesn't really belong in this mode!). The performers were expected to adjust the notes during realization. Couldn't change the whole system without the church rearing its ugly head.
Beethoven tried a Lydian quartet (No. 15, a Minor, Op. 132). It's still basically in F major, despite the stubborn attempt at avoiding "B." Diminished chord on IV in Lydian, though. Pretty difficult, even for Ludwig.
