AFAIK, there is no way to customize the output of the built in stat block.
There is a way to create an entirely customized character sheet and
AncientOne has created such a sheet. See
this thread. It's not perfect as it parses the XML output that HLC generates and HLC doesn't indicate which gear items are inside of a container, so you lose that information (and multiple bug reports on this have gone unanswered by LoneWolf, so it won't be happening at this point). Otherwise, someone with knowledge of HTML and JavaScript should be able to reorganize the content in pretty much any way you want.
Not the answer you were hoping for, I'm sure, but I hope it helps.
