The main reason I'm okay with fixed engines is to due with examples like the Raven, where one of the few differences between the variants is engine size.
Also thinking about it realisticly, the engine that is in a mech would be hard as hell to take out, would be designed for one brand and size and type of engine. Take a long hard look at mechs like the Raven and Bushwacker, their tosos are crammed full of armour plates, skeletal structure, weapon mounts, feeds for weapon systems, power cables, cockpit, computer systems, gyroscope and an engine. I wouldn't be surprised if every millimeter is accounted for in side of them. To use a real world example, you cannot take out the engine of your car and just drop in a larger engine from a different manufacture, with out having some major issues.
I used to have some of the "schematics" that showed how stuff worked in some of the original IS models like the Atlas and Stalker. Never really saw one for an Omni. But the ammo feeds alone make some of the stuff we do here completely ridiculous.
But as for swapping engines...Think about whatever car you're driving. Whoever designed it, designed it with a certain size in mind. If someone figured out how to increase the displacement (and thus the power) and keep the same size, it's a more powerful engine. The concept is sound and since we're talking fiction, I think it applies. Hell, after the Invasion, a lot of older models were retooled to use newly developed tech. Lots of XLs replacing Standards...and that's taking a lot more engine space. So, it can be done. It's just expensive and pretty time consuming, which means the IS can't do that kind of extensive repair in the field.
Omnis, if you read any of the game sourcebooks or some of the novels, are supposed to be the next evolution in Battlemechs. Everything modular. Plug and play based on pod space available. Plenty of examples when engines were replaced in the field with Omnis. One would think you'd be able to "downgrade" the engine and open up more "pod space." Which is pretty much the remainder after you put together the structure, armor and engine. More or less. Mechanically speaking, when writing one up, that is.
