Why would it require the factory? The idea of refitting engines for xl engines in dropships, and even repairing them in the field is completely canon. Admittedly, it's not going to be performed under ideal conditions, but it can be done.
Repairing is easier than refitting. Repairs can certainly be performed in the 'Mech bay. However, refitting a 'Mech with a different engine rating requires a good maintenance facility(Class D). Furthermore, changing out to an XL is one of the most difficult things to do to a 'Mech, being in the same category as replacing standard internals with endo, changing out the gyro or changing out the cockpit type(Class F). The rules for this can be found in Strategic Operations, which is in the rulebook set which is the most current(and will likely remain so for many, many years). The page to find this info is on Pg 188. Be sure to check Pg 189 to see how a completely custom variant modifies the difficulty and time.

The Master Rules on page 91 lists the total replacement time of an engine at just 360 minutes. That's 6 hours from start to engine calibrated and battle ready.
I need more details on which book than 'the master rules'. Also, replacement of a damaged engine is NOT the same as shoving in a totally different sized engine.

Now retrofitting a larger engine or an xl would require access to a machine shop to fabricate the specialty parts, mostly new mounts, and may require the removal of all the armor on the back of the 'mech for access. So a more reasonable estimate would be a total turn around of a month in the styx with makeshift equipment and the tech phoning it in. A week to 2 weeks in a properly fitted 'mech bay or fully equipped dropship. And under a day if you have access to the factory, where you can grab a half completed chassis and a dedicated crane. Mind you, this is just for the engine. Any other changes will add their own replacement time to the mix.
Internal structure isn't simply machined steel. To say that producing custom battlemech parts is more complicated than firing up your friendly corner machine shop would be a masterpiece of understatement.
I didn't just pull 60.5 days out of my nether regions. The math was performed. If you'd like to backcheck me, I've given you the book and page number required to start you off.

All of this is just a long way of saying that I am a fan of custom jobs. I just think the game should include incentives and rules in place to keep the designs on the side of canonical and away from the absurdity you got in some of the earlier games.
I don't mind custom jobs if I feel shock and surprise when I see one. Holy crap, that's a custom! Throw out the rules I've developed for dealing with XYZ 'Mech because this is a whole new bag of cats! The only way to do that is to find a way to limit the number of them played. Making it so it's hard to break a profit in custom machines might fit the bill.
