That's a bit unorthodox but it will work.  In Qimage, technically you can choose the same Ilford profile as your printer profile or you can select OFF for printer profile: both will produce the same results.

A better way would be to use the original colorspace of the image (the camera profile) but I'm not sure C1 lets you do that.  If not, use Adobe RGB or ProPhoto RGB.  That way, you can select the printer profile in Qimage and you won't be just limited to the Ilford paper: any paper profile you select will work.  As you are doing it, you're really limited to just the Ilford paper when you print.

You can export as Adobe 1998.  The soft proofing profile is only there to simulate what it should look like on paper.  That should not affect the editing profile.  I'm not a fan of soft proof editing.  You should be able to get great results just editing so that things look good on your monitor (without soft proofing).  Then when you print, the printer profile will take care of any differences.

The only time I resort to editing based on a soft proof is a 1 in 1000 print where I just can't get a certain color to match and I have to make compromises.  Soft proofing requires an accurate monitor profile and printer profile and most printers have at least some colors that are beyond the gamut of your monitor: so those cannot be displayed accurately in a soft proof and they can throw off your results.

Bottom line: only use a soft proof when you need it... when you see a problem.
