Perhaps a case could be made that engines in the pods would not
require nearly as much access space as an internal short-occupancy
installation?
What if the engine stats in Ve2 already include the minimal
maintenance access space necessary for components built into pods?

Pods place the access space (or at least most of it) outside the vehicle,
at a hefty penalty in surface area compared to a car engine, say.
Precisely.
I think the main question here is whether or not it is worth the
extra complexity to add a small volume fraction of access space
within the pods.. Based on a few jet engine pod pictures, it would
seem like about +20% to +25% volume or so.
As the pods are usually fairly small in relation to the vehicle
they are attached to, I don't think the +25% of access would
actually result in any noticeable differences in overall vehicle
performance.
Also, I would not be too certain about placing an upper limit of
500cf (one hullspace) on engine pod size.. Check this picture out;
<http://www.aerospaceweb.org/question/planes/q0046a.shtml>
This looks like a fairly new approximately 2 hull space volume
jet engine pod.
Seems that jet engine pods (not to mention the planes themselves)
have been growing in size as the technologies have improved..
I don't think a hard and fast fixed upper limit on pod size would
work well with Ve2, not with all of the TLs covered anyhow, and
not for all conceivable types of vehicles.
Some kind of an extra rule or guideline on how big a jet engine
pod can be in relation to the fuselage size could come in handy,
however. For one, it would seem ridiculous to design a pair of
jet engine pods with a total volume equal to the body size..
