I did something similar for PXE scenarios but eventually decided I was
spending more time coming up with clever ideas than I would have saved
making use of any of them. The approach I took was to write a custom
loader.rc (with an include for each of the possible options), but IIRC
everything was presented via a rudimentary menu.
For customising the existing menu, if you read through loader(8), and
then have a look at what's provided in /usr/share/examples/bootforth,
you should be able to figure things out without too much trouble.
