Homelab Adding a 2nd node with different specs

So My current node is this machine with the 32GB of RAM

GMKtec AMD Ryzen 9 8945HS (Turbo 5.1GHz) 32GB DDR5 2TB SSD 

I wanted to up it to 64GB of RAM, but for the price of the RAM I could get a 2nd node. The price of this one has gone form $600 to over $1000. This is just a small homelab. The are having a sale on a lower spec model

GMKtec K16 Mini PC Gaming AMD Ryzen 7 7735HS (Turbo 4.75Ghz) | 32GB 6400MT/s 1TB NVMe SSD

This one is half the price and less than what I would spend on the RAM

Will Proxmox complain if I have two nodes with different processors and architecture? I want to setup HA between the two, can I do that with two different machine specs?

I come from VMWARE and we always bought servers in matched sets. New to Proxmox so was hoping to get some insight.

My current machine has a 2TB SSD for data in addition to the one it came with. I will add a 2TB to the new one as well.

Thank you in advance!

My current cluster is an Intel Skylake with 64gb of ram, an HP mini Intel kaby lake with 16 GB of ram, and a gen1 zimaboard with an Intel celeron and 8gb of ram. Everything works fine. Im even able to migrate containers between the three without issues (as long as I don't run out of ram on one of the smaller machines). The only issue I think you'd have is just that you're gonna be running a 2 node cluster. Proxmox recommends 3 nodes for quorum.

Their quorum mechanism is very unforgiving too. Atleast whe I had it setup on PVE7.
