You might consider using an AUDIO Filter. It will be compatible with almost any rig. It would not perform as well as an IF Filter, but it should be worth the effort. 
MFJ?  I might even have one in my shack which I am not using.

 HI Folks;
 I have an IC706mkIIG that for the most part I really like,
 however, it 
 does not have any filters of any kind in / on it.  I am
 planning to 
 replace it as soon as I can, however between now and then, I
 would like 
 to come up with some way to filter the received
 signals.  The radio has 
 2 slots for icom filters which are very difficult to find
 (at least 
 according to vendors at Dayton this year) (and when you do
 find them 
 they are expensive) I was wondering if there was a way I
 could tap that 
 signal chain at the filter slots and take the signal out to
 my computer 
 for audio processing, and then either hear it directly from
 the computer 
 or return it to the radio for further "voodoo" before it
 gets to my ears.
 I'm not very familiar with receiver functioning nor audio
 like this so this is kinda stretching my limits a bit here
 as far as 
 technical stuff goes, so I might need some in depth
