Would you be willing to type up a bash script along the lines of:

https://github.com/linux-netdev/nipa/blob/main/contest/tests/build-doc.sh

perhaps some inspiration from:

https://github.com/linux-netdev/nipa/blob/main/tests/patch/build_allmodconfig_warn/build_allmodconfig.sh

? (the former runs on the test branches the latter commit by commit)
