Working it out, the only way I could see the X5/X15 going X-Lines without significantly impacting the number of spares available would be another service being reduced.
If the 56 was permanently reduced to every 15 minutes (PVR 11 + 1x spare) and 6096-98 alongside 6099 was allocated to the X5/X15, that would be do-able but would leave Consett with only 2x X-Lines spares covering a PVR of 30x. Plus that would only mean 1x low height decker and 1x Gemini spare.
However, something like the following could perhaps be done.
