I also vote for linerless G10. The liner should be necessary for the clip rather than for solidity reasons. But what I have in mind, is not any regular clip you're currently using, but a different one (could be wire clip or not), fixed "vertically" with a screw in the backspacer (like a pen, if you like). It will make the knife go deep down in the pocket, keep a very low profile and the head of the screw (torx and rounded, so it won't wear off the clothing) might be used as a striker / glass breaker eventually.
The blade should stay at its current thickness (2.5 mm). A bit more belly at the blade would improve cutting IMO and it will make the knife look like a smaller Military - I'm drooling for such a long time for a Delica size Millie
As about the full flat ground, I'm not sure. I made a full flat ground to my SE Delica and it performs well. No tip problems, though I used it for throwing as well
That VG-10 steel is really great. Yet, I am pretty satisfied with the hollow ground of my ATS-55 Delica or the flat ground of my CF Delica. The blade is thin enough so the geometry doesn't make much difference (IMHO).
Edited to add another small mention concerning the pivot pin. It should be an adjustable one, just like the CF Delica.
