Sure, but I think you'll agree that calling this modified version RSA is a bit of a stretch :)
Every definition of RSA I've ever seen requires d and e to be coprime with λ(n)

d=4 is not a valid RSA private key.
When p and q are prime λ(n) = lcm(p − 1, q − 1) is always even. e must be coprime with λ(n) so it's odd.
de ≡ 1 (mod λ(n)) which means that de is 1 + an even number, so d must also always be odd.

You can already load your own microcode, and it also works on newer CPUs than the one that the attack described in the OP targets. https://github.com/google/security-research/tree/master/pocs...

The joint entropy of two random variables is never less than the individual entropies.
