I'll keep it short. I have, all in good condition,

2 x 100ah SLA, 1 x 102ah Silver Calium, 1 x 93ah Enhanced Flooded (EFB) - I'd like to serial then parallell them to my 24v inverter.

I'm aware that:
Silver Calcium and EFB charge at a higher voltage than regular SLA.
There will be back & forth & reverse charging somewhere in the bank.
Batteries will discharge at different rates.

Everyone's thoughts?

I lolled. You are right. I'd just like to preemptively guage the degree of sadness prior to actually going through it.

On a scale of 1 to 10, your sadness will be a solid 8.

The sealed lead acid and the Silver calcium battery are at opposite ends of the charging voltage range. I give it 30 days before they are all dead. Maybe the EFB could be revived when you are done, maybe.

Noted. Well noted. 0/10 won't actually go through with this....

Further evidence that lead acid is at best, stressful. Archaic tech. Time to accept the costs of one's ability to store power.

Not my perspective, I love lead acids. Simply the most reliable, cost effective and consistent battery for my purpose.

Get the batteries you actually need for your purpose.

I have a hybrid SLA and LiFePO4 set up but it's been well matched to be compatible and designed for a specific purpose. 19 months of operation in this configuration and working well.

Indeed. Saving up for a lithium. These are interim.

5-6 years ago I got the "You can't do that" speech when I built my hybrid CG2 and my diy LFP trailer system. It is still going....... With that said as you well know series is a bigger challenge. Perhaps the use of battery balancer's could help in your adventure? Charge them individually once a week and extrapolate the best over all settings? Good luck with your adventure and please update your progress!
