IMO, while you should take care to not grossly violate the known universe, obsessing over details like which version of the T-bolt (which, BTW, isn't jump capable as of WC3/4, though possibly is as of Prophecy/Secret Ops, where most ships seem to have jump capability) to use detracts from the story, instead of enhancing it. Sure, technology is an important factor in the WC universe, but ultimately it's the people that really matter.

Also, flying a solo fighter behind enemy lines isn't the best of ideas, in general. Something like Paladin's Bonnie Heather from the WC2 addons (and Fleet Action, where it has a cloaking device it used to get in close enough to scan the Hakagas being produced, before and during the False Peace, on the far side of Kilrathi territory) would be better, as it wouldn't be as likely to attract attention.
