I just googled Lionel to see his previous IM marathon times and saw something that said he was 5'10". I've stood next to Lionel on more than one occasion. If he's 5'10" then I'm 6'3"... and I'm not 6'3". I recall the first time seeing him at the Panama 70.3 a couple of years ago and thinking he was much shorter than I had anticipated.
Sorry for the random thread derailment.
I don't think he could run a 2:30. That's about 13 minutes faster than his IM mary best and elite athletes like Lionel don't have as big a delta between an IM mary and an open mary like us mere mortals. But it's certainly possible.
