They've already butchered Leisure Suit Larry with their two latest "games", whose titles I can't be assed to remember. Lowe wasn't involved in either of them, and it's obvious that whoever owns the rights (Vivendi I believe?) isn't keen on bringing him back in. The sad fact is that unless Al Lowe is given authority over a Larry game, it's going to suck.
As for adding voice overs to the originals - it'd be a neat idea assuming they could get the guy that voiced Larry in LSL 7 and LSL's Casino, but I doubt they see much (if any) market for the games anymore.
I've still got the original LSL 7 Scratch'n'Sniff 2000 card sitting in a box near my desk. Ah the memories! 
I can never be free, because the shackles I wear can't be touched or be seen.
