The Beguiler has more skill points, has a more spontaneous form of casting and has more spell uses per day.
If you want to match the Beguiler's casting with Sublime Chord or Lyric Thaumaturge, you only fall further behind in skills. If you want to multiclass to match it in skills (I can't think of an 8+Int full casting PrC), you fall even further behind in casting.
The character's abilities would generally remain the same, but Beguiler advances to bigger and better powers more quickly.
...Just a thought.
That said, I'm probably going to contradict myself by going the opposite direction and use your idea, substituting Lurk for Bard.
