John Carmack had several posts about doing exactly that and maybe even
lower pressure. You should be able to find it by searching the archives.

Hello all,
Are there any issues operating at a relatively low chamber pressure for an
engine ~180-220psi other than the poor Isp. For a pressure fed rocket with
a relatively high thrust to weight ratio the benefits of using a lower
chamber pressure are really tempting, but I imagine there are some design
challenges that I am unaware of. My main concerns are difficult ignition or
possible flame out but I don't really know.
Thank you,
