Image builder TL-WA801ND-v2

hello. i have a TL-WA801ND-v2 repeater with openwrt 18.0.6 initially 4mb flash and 32mb ram i soldered a new eeprom and new ram and now it's 8mb flash and 64mb ram.
I want build and image from the latest build or at least v19 the problem i cannot target this device from the builder because it's not supported anymore.
Is there a solution to add this device?
sorry for my bad English

it's doable for both 19.07 and 21.02, using ath79, since Ashus' making minimal 4mb flash images for those devices - OpenWrt 19.07.1 ath79 tiny LuCI
