Chain device help needed

So, im trying to convert my 2014 saracen mantra to 1x and not wanting to spend much money (another bike build underway) im staying 8 speed at the back and running a shimano chain device via a BB mounted iscg adapter.
When i removed the bb (a CH-52 square taper not removed since new) there wasnt a spacer between the driveside "collar" of the bb and the frame. So fitting the iscg adapter has spaced the bb about 3mm off centre towards the driveside, some thing i hadnt considered before i came to refit my cranks.
When i refit the crank (some RPM El Torros i had spare) the chain ring sits too far away from the chain device. I have the chain ring fitted behind the tabs on the cranks and i have spaced the CD  about 3 mm out from the adapter but its still quite a way off. I guess this this down to the bb now being off centre.

Does anyone have any idea on how to sort this? Would going external bb and hollowtech cranks be a quick and easy fix?

Re:

A wide narrow ring from eBay with bolts is less than £20, must be worth a go rather than faffing around with chain devices?
It’s the way I’m going.

You could space the ring, but i would go with a narrow wide ring, you dont need a chain guide then.

I have been running one over alsorts of terrain on a hardtail, never dropped the chain once, very good peice of kit.

Re:

I am running a narrow/wide chain ring but still went with a chain device as the rear mech isnt a clutched one so i thought a cd would be necessary.

Some people say you need a clutch rear but plenty of people run one without, including myself, and have never had a problem at all.

Just google Narrow Wide and clutch rear and you will see loads run it without, even on full suss frames
