a 10" makes lots of noise of course, and yes, why not trying one of these 50W monitors.
if you want to crank it up together with real drums you might use a 12" which is the standard guitar speaker dimension. but I guess you don´t really need it thou
as i said, all of these are in the right direction, as they are built less or more to transfer the sound of the pod as is.
you won´t be altering the tone caracter in general with them really, as the pod is the one who delivers the default sound.
the only diference would be in the quality of the speakers, like if one of the horns is transducing better highs than another. But it might be marginal only, depending on your demands.
If you are not sure, you might try it and send it back if you dislike it.
Just go for a try and you´ll see
