This sounds like a good approach to me.

Right, I have already defined a structure for this type of messages
but I can't get olsrd to transmit this struct.
I currently simply merge the client's lease-files to spead news about
new IPs and MACs.

I would be glad if I could test my implementation, to see if there are
design flaws or something similar.
There were some concerns if we need an extra real interface or VAP is
enough. I use a VAP-interface. Basically every atheros-wifi-based
router should be capable of this.
Feel free to look at the current source at
http://github.com/ralisi/olsrd_cl_roam but please be gentle because it
is the first time other people look at my program-code.
