Firestorm and Black Goliath

I read with interest that Laurence Fishburne is going to portray Bill Foster in the upcoming Ant-Man and The Wasp.  Will he be there in a professional capacity only, or is there a chance that we will see his super-heroic side?  Fishburn may be a bit too old an out of shape these days, but Marvel has demonstrated their ability to de-age actors for flashback sequences, so maybe they will surprise us.
