Can you make up the lost capability of the Ticos by just building more Burkes? Say 3 Burkes to 2 Ticos? Can quantity make up for quality?
If it were just a matter of VLS cells, sure, and it would help overall numbers. But the fleet would still lose the command facilities and associated spaces the CGs have, the gigantic Ship's Mission Centers on the 3 Zs will be the only decent command facilities not on a carrier or LCC. Whole lotta people, even many who should know better, try to handwave away the problems of cramming Alpha Whiskey, or a SAG command staff, into a
Burke's CIC for the long term. I'd also point out that command hulls should have additional survivability, which an overloaded DDG-51 hull would not.
Then there's the generational problem of new, larger, more power-hungry systems coming into the fleet. Even if we're not going to do "cruisers" anymore and don't care about the command issues, we can't stick with a 1980s hull much longer if we hope to carry 2030s and onwards weapons, sensors, ECM, etc.
