You can swap to a square port engine very easily... you literally only need the 87mm truck square port intake and all else bolts right in.
The Iron block square port motors can be had a hell of a lot cheaper than the alum 5.3 can. And it makes a hell of a lot more power.
After selling the block and the heads you wont be into it for much... less than 1k.

Dude I did this exact build with a 5.3 Saab that I turned into a 6,0 with anL96
It ripped. It had an LS6 cam and a 3000 converter. The cam left a lot on the table without a doubt. But the car ripped. The LS6 And LS3 are very similar but the LS6 has more exhaust duration believe it or not.
That's the route is take again without hesitation. Sell The parts off the 5.3 for what they're worth and move on.

I am seeing a few resonable,by resonable I mean not stupid money for 100k mi L96s on carpart and will have shipping costs.Summit has a baby TQ cam decent priced and good Ol LS6 spring are a good deal.

You tell me if you think "cost me a motor" was an over statement.
He recommend 1211x PAC springs for my 2010 Silverado 6.2 LS9 cam and boosted and had ARHs
spring broke,dropped valve less than 20k miles,took out a piston and a head.So then it all went back stock.Talked to 2 other "gurus",they said that was not the spring for that cam,better off with LS6 springs.
