You should still be able to use peek and poke to access RAM. You wouldn't be able to allocate it, but you could at least find an area that was free and pray.
However it's worth noting that typed arrays (apart from a 16 byte header) store bytes 1:1 - so realistically you might as well just do a big
new Uint8Array(...)and save yourself a lot of trouble :)
