ache> (btw, what is slaac?)

It is abbreviation for StateLess Address AutoConfiguration described
in rfc 4862.
This RA option is described in rfc 5006 (IPv6 Router Advertisement
Option for DNS Configuration).

ache> And I want to override <IPv6 DNS address for the router's IPv6 tunnel> 
ache> with simple link-local IPv6 address of my router, i.e. fe80:...

I think your network admin setup to advertise the address.  Why do you
want to use link-local address, instead?

ache> Is it possible with resolvconf(8)?

resolvconf(8) doesn't have such rewrite feature.  However, rtsol(8)
has -R option to specify your own script to update /etc/resolv.conf.
You may want to write your own script to rewrite nameserver address
then pass it to resolvconf(8).

Sincerely,
