It's perfectly possible, and is what has been done, to make themes adapt to changes in the WinXP skin, in terms of colour and overall look. Unfortunately, it doesn't seem possible to make firefox adapt the different padding that buttons use.
The current issue is that if you basically, use a WinXP theme, apart from looking all colourful which isn't so bad, you also get buttons with a stupid amount of padding IMO that wastes space. Now, if an application like Firefox then has this stupid amount of padding and you are used to/using the classic/unskinned theme, then it throws all your normal UI control out of the window. Personally, I find that a lot of the control you have over a UI is automatic and you get used to things having a certain dimension, therefore, when using Firefox with the extreme padding, you end up misclicking or just getting annoyed at the 'wrong' feel of the interface compared to what you are used to. IMO, this is actually far more important than the icons themselves as it makes the UI feel 'wrong', at least to me.
Obviously, you might get used to this padding over time, but for new users to the theme it is the first impressions that count and since this is the default theme, it's not only the first impressions of a theme, but the whole browser.
