The latest (28th of December) copy of Doctor Who Adventures (thanks to the denizens of the Crooked Dice Forum for pointing it out) has five iDaleks and six RTD era Daleks.
The above shows them, with a comparison for size with a Harlequin (BTD) Dalek on the left and a Tweedy Mattison on the right.
As you can see they are both tall, the iDalek is possibly about the right size, the RTD one (designed to be eye height on Billi Piper) is rather tall.
They will both need dismantling and the front plate glued in properly.
