I haven't logged on in awhile, but I thought I would share my observations on using these htrs. Hopefully, it will come in handy for a few people who are having problems with hap files.
When a full body htr is started, it uses an internal name for the figure. 'Fullbod.htr' and 'fullbodygirl.htr' use 'fullBod'. 'Body_female.htr' uses 'body_female'. This can be checked by entering 'current figurename' in the Query field of the console. A lot of the hap scripts used on this site have 'figure=fullBod' hard-coded in them. This means, of course, that the 'body_female' will not do anything. But, you can trick the 'body_female' into thinking it is 'fullBod' by entering the following command:
setname [figure= body_female name= fullBod]
Most haps should now work with "jiggly".
Beware, translate (and probably rotate) does not work the same way in these htrs. 'Translate X' and 'translate Z' have opposite effects when entering numbers. see below:

If you do not use translate, the same hap script should work for both. Here is an example (body_female on the left, fullbodygirl on the right):

(modest, aren't they?)
Does that help anyone?
Comments, questions or concerns are welcomed.
