Adjustments for short arms for R forearm on shaft plane

[JackieTreehorn]

Are there any suggested adjustments for players with short arms (and long torsos)? I'm specifically thinking about getting my R forearm on plane at address.

So far I've noticed pulling the L arm across to the right PLUS increasing my reverse K (returns hands forward to L hip) makes it easier to get R forearm on plane at address.

Also, more spine angle seems to give more room for my arms to operate.
