You should definitely learn about targets. You can use MakeTarget to make a custom target that you can use in MakeHuman to create disproportionate body parts, and when you export with a skeleton the skeleton will be scaled to fit properly.
In MakeTarget you can load one or more existing targets, like the built in limb size targets etc., apply them to any factor, and then save the result as a new custom target. For example, you could load the upper leg length target and the lower leg length target, apply them as shape keys with a factor of three, and then export a new custom target that allows you to scale the length of both simultaneously, and by triple the amount the built in targets do. When you apply the custom target and export it the skeleton will automatically be correctly generated.
An advantage of using the built in targets this way is that it will handle fitting clothing as well as the skeleton without you having to deal with the clothing helpers, which is a whole other topic.
The above may not be entirely coherent, especially if you aren't familiar with MakeTarget, but take my word for it that MakeTarget is a tool designed to do what you have described you want to do, so look up the documentation on it and have a go at it.
