I'd be suprised if the lack of infocus was as much as 1 inch. You said your star blur was starting to come to focus. I'd say you might only be looking at needing another cm at most. Assuming thats the case.....First thing to try is to decollimate the primary to move it further up the OTA. ie. loosen up the collimation bolts several turns to push the primary further up the tube. Re-collimate and try to bring the camera and BV to focus. If its still not quite there loosen the collimation bolts a bit further. However, this time you are going to have to be careful that you don't unscrew them too far where they disengage/unscrew from the mirror cell entirely. So now just do 1 turn each, recollimate and check focus etc.
If you now find you can reach focus, tighten up the locking bolts till they just barely touch the cell. In future when you collimate, decide which collimation bolt is easiest to remember to never touch again. I decided on the bolt on the focuser side of the OTA. In future only collimate with the other two. By leaving one untouched, this will mean the primary doesn't start migrating up or down the tube over the course of several collimation sessions.
The downside to this is that if your lack of infocus necessitated moving the primary so far up the OTA that the collimation springs are barely compressed your scope might not hold collimation very well and collimation might drift when you move the scope in altitude. Another slight downside is that if your secondary mirror is not slightly oversized, by moving the primary up the OTA, the secondary might not be able to catch the full light cone which isn't a disaster but it means your are losing some light and losing some contrast because of a larger relative central obstrusction.
If you only had to lossen the collimation bolts a couple of turns though, you should be OK with regards to all those issues. Most Chinese Newts have oversized secondaries anyway.
Another option is fitting a lower profile focuser. If you felt you wanted to upgrade the focuser anyway, then the cost of this option doesn't really matter, however if you don't want to spend that kind of money then there might be other options. Is the focuser a 2" or a 1.25"? If its a 2" is there a way to use your camera and BV in the focuser in 2" mode without the focusers 2-1.25" adapter? This could give you the infocus you need.
Another option if your camera and BV will only fit in the 2" focusers 2-1.25" adapter is to buy a special kind of recessed 2-1.25" adapter.

This could give you the infocus you need.
The option of last resort is to shorten your OTA by cutting a slice off the rear of your OTA and refit the mirror cell.
