The increased exits would also actually lower our capacity for CL games.
The determining factor is evacuation time for which there are other factors but on the face of it, yes, it would.
Nevertheless, the loss of revenue on the smaller number of seats should be factored into the increased revenue from the larger standing capacity.
As I said........
Current seating has a seat pitch (the distance front-to-back) of about 600mm. Safe standing rail seat requires a pitch of 800mm! Hence your current 50 rows of seats reduces to 38 rows.

There are no guidelines for safe standing in the UK or how much space is required front to back (other than the agreements reached at Celtic...).
Guidelines still applied in England and Wales for traditional standing have a minimum step of 280mm for an existing stand. At a given minimum height of step, this is deemed a safe pitch with barriers at a certain distance. As it happens, the Kop can accommodate traditional standing in terms of the basic structure, steps, angles but not of course barriers. Rail seating has barriers
every row of seats or every 2 rows of standing and hence is inherently safer than traditional standing.
The UK Green Book also recommends a minimum clearway of 305mm in front of any seat (in the down position in this case), which with a seat size of 245mm would require 600mm step depth (including 50mm frame). At Celtic, the existing stand happened to be 700mm and the seat size and clearway were agreed accordingly.
So I don't know where you're getting the step depth from but if rail seating required a step of 800mm, you would be talking about re-building the Kop, which would defeat the economics of the situation by a country mile.
Two standing rows per seat:
