Very reasonable indeed.

If you want to send GPS data on a regular interval then you should
register a scheduled event eith the olsr scheduler. If not, you can just
pass the data along immedeatly as you receive it.

Quick answer: Yes. (but that is only in theory ;) )

All to parse OLSR messages you must register with the packet parser to
receive a certain type of messages. Forwarding of messages is done by
olsrd according to the default forwarding algorithm.

Parsing and forwarding messages origination from ourself will lead to
loops! Is there any particular reason you want to do this?

And a happy new year to you to :)
