I spent some time looking into using kexec to have one kernel load a replacement with the idea that the recovery menu could have options added but didn't get it working. Having an adapter for the debug serial port at least on htc's phones would be useful to get output while figuring out where the process is failing.
As a caution you only want to monkey with one kernel at a time (either normal or recovery) so that when ot doesn't work you can use the other to reflash it - unless you have an engineering bootloader. You could also try to port u-boot - easier to the serial port first, then worry about onboard display and input.
