A 4th member of the Space Sheriff family would be good to see for a change.

The fun thing about metal heroes is there are sub categories within; space sheriff, mechanical cop, hitech rescue to name a few.
But if they are bringing it back they should start with a space sherrif and then make a new Janperson/Jiban type hero and then the successor to Winspector, Solbrain and Exceedraft.

Then they wrap it up with Japan's Avengers film Metal Hero Taisen.
