Traffic shaping on a BGP session

2 routers from 2 different AS are connected through 2 ATM virtual
circuits.

                  |  AS1717  |            ----------C1---------          
  |  AS5511 |
 INTERNAL |       R1     | ---------|                         
|----------|     R2      | EXTERNAL
                                               -----------C2----------
              
EBGP Peering is set between  AS 1717 and 5511. 
We would like to do traffic shaping on the incoming trafic on the two
virtual circuits : All routes but a few shall be annouced via circuit 1;
the remaining routes shall be annouced via circuit 2.

We were planning on doing it via route-maps, however there is only one
BGP
peering between 1717 and 5511; another solution would be to set up a
static
route on R2 to reach the last route via C2.

The former solution would be better while communities could be used to
select the "remaining" routes.

Questions :
Is it possible to set up two BGP peerings between the same AS (i.e. two
BGP
sessions between 1717 and 5511) ?
Can one think of any better solution ?

Thank you for your help.
