Electrical panel question

If I do any modifications to the conduit length, then I'll have to talk to the county and PG&E about extending the feed length because there's no way it'll be long enough if I add a couple of 45s to the existing conduit. Even if I'm able to do that, if I run into any sort of snag along the way, it could lead to me not having power for an extended period of time. I just don't know how deep into customizing this I want to get because of that very reason.

I started thinking about seeing if I could buy a meter socket that connects directly to the existing conduit and then running a short piece of conduit above it that connects to a subpanel. I'm not even sure if anything like that exists, at least in a flush mount form. Definitely not finding anything on google so far.
