That's much too small a scheme for Lazarus, if for no other reason than Eyrie doesn't actually make any money on this stuff. If you were raking in the cash, that'd be a different matter.

Besides, Heinlein self-inserted himself, twice, in TNotB if I remember correctly. So he might have issues with Lazarus going after his copyrights. Lazarus was Army, Heinlein was Navy, there's no way LL would 'slum' as a squid, so they have to be two different people.
