How do I fillet this thing? District9 Platform

Working on a Personal Project to release on Sketchfab:

I tried to replace the platform I did in Softimage with one out of MOI.
I created a text where I extracted the Edges to project them onto the platform`s Surface. Everything went fine except for the 9. Which seems pretty hard to fillet.
Is there a way to fillet it anyway ? I tried to Draw a circle to do a sweep, but i cant seem to rotate it to the place where the failed fillet sits. Maybe you get what I mean by looking at the screenshot:
