My thought is yes.

I say, copy it to the request scope (Or even the variables scope). Make
sure you use the duplicate function, otherwise you are just copying a
pointer and all access will still need locks (if that makes sense?) .

I'd recommend running some numbers to see how they turn out. You might
look at it this way:
Everytime you call a CF tag, you make a call to a C function.
<CFLOCK>
<CFSET request.tempsession = session>
</CFLOCK>
You made two calls, here. So, the break even point is when you make two
calls to the session variables. This, of course, assumes that all CF tags
take an identical amount of time to execute which is (obviously) a flawed
assumption. It may give you food for thought or a point of reference, though.
