If you have a bin of Jiffy DOS and can burn a copy in an EPROM ... and

.... what was the original request for:

I'm making an assumption that it's impossible for a stock C64 w/ 1541
to auto load when C64 is powered on. The stock kernal makes no disk
boot record check like the C128 w/ 1571.

So we need to modify the kernal but once you start mod'ing the kernal
you need a prom programmer.

My question is this - is there a way to program a new kernal on-board
(ie without removing the chip)?

I still think the assumption is not true ... if you have a cartridge
port pass-through with a chip that brings itself on reset to execute
the boot and then on the read of the last byte of the routine latches
itself out until the next reset, that's an autoload on a stock C64.

But surely if you can program an EPROM, that's easier than building a
board to allow in-circuit programming of a parallel Flash RAM.
