DOHC bottom with SOHC top?

[Marahutay]

I have been driving a stock 91 ka24de daily for almost a year now, and stumbled across a sohc motor+transmission.

i need new pistons/rings for my ka24de (burning oil) before i can do my turbo. i figured i could just swap the pistons and be good. but. after research found that it siginificantly increases compression ratios due to the smaller cc of the de motor vs the flatter pistons from the e motor.

would it be possible to keep the bottom end of my de motor, and put on the top end of the sohc to replace the pistons and keep a safer lower compression ratio?

would it be safe to run pump gas with the compression ratio of the sohc pistons in the dohc block as a high comp N/A daily driver while building the sohc block as a side project? ive heard many people say yes and no.if so, is there anything i may do when swapping the pistons to slightly lower the compression raito for a small cost to make it more reliable such as a thicker head gasket i know will give a little more room for the piston.(currently on limited budget or i would buy forged pistons)

and on a side note. if i were doing this backwards, would dohc pistons in a sohc provide a prime compression ratio for higher boost on stock parts?

or am i crazy?

any suggestions and info is much appreciated
