In Commodore BASIC there's already SYS, which lets you jump to an arbitrary address anywhere in the 64k address space, including ROM. You can even include raw bytes in a BASIC program and have the CPU execute them as machine code.

however encoding such program in BASIC would take much more amount of commands/bytes than writing it in BASIC itself. You would need DATA statement and POKE FOR LOOP... In case of such a small scenario BASIC wins

There are ways around that too... store bytes in a string or a REM and then execute it directly. No DATA or FOR needed.

There were some workarounds posted on of Robin's recent video.
