You didn't mention what camera you were using other than it was Canon and a crop sensor. If you are using a Canon DSLR with EF-mount, then the flange distance is 44mm.
If this is the case, switching to a mirrorless camera would give you a much shorter flange distance and get the camera closer to the scope so that possibly, the barlow lens might not be needed which would give you a much wider FOV, even with a mirrorless crop sensor camera.
Which mirrorless camera to use is another question. I will use Sony as an example since that is what I already have. You could explore if there is an option like this for Canon mirrorless.
There are many Sony mirrorless cameras that could be used. They all use the same E-Mount. And the flange distance is only 18mm. This is already 26mm closer than a Canon DSLR camera.
Then you need an appropriate T-adapter. Assuming that you stay with a crop sensor body, you wouldn't need a 48mm wide T-Adapter and can get by with a 42mm wide T-Adapter. I assume you are using a 42mm to 1.25" nosepiece adapter so that it can be plugged directly into the telescope eyepiece socket.
T-Adapters for mirrorless cameras come in two different length. The normal E-Mount T-Adapter is long enough so that when you attach it to the camera, it ends at the same distance from the sensor as a much thinner T-adapter on a DSLR would end. THIS IS NOT THE ONE TO USE. This is used when you need a field flattener and it is required to have this field flattener be 55mm from the sensor.
What you would need is a thinner T-Adapter. This one is 42mm wide and 10mm thick:

Ot even better, a 48mm to 2" nose piece adapter such as: (provided you can use a 2" focuser on your scope)

Using a mirrorless camera with the thinner, 10mm, T-Adapter, you can get the sensor 26mm closer than using a DSLR.
Now it is fairly easy to find out if 26mm closer is enough to achieve infinity focus, provided you can find a friend who has a mirrorless camera. All you need to do is to set the scope for its farthest focus and to place a mirrorless camera without a lens above the eyepiece socket (without the barlow) and to then move it away maintaining it to be inline with the eyepiece socket. If you can watch the LCD display and find a spot that comes into focus, then you will know that it will work.
I don't know if 26mm closer is enough. But it might?
