 I'd say that such a question underestimates Tolkien.  What you are suggesting is that trading in mystery for endearment is a good exchange in your opinion.  I contend that the trade-off isn't necessary.

You need to indicate which wizards you are talking about in which stories.

   It's a minor issue; at the risk of going off on a major and useless tangent, the Celtic wizard is druidic, his milieu that of human sacrifice and unity with nature.  The Germanic/Nordic (I must include the term) wizard with control of the elements - earth, wind, fire, ice, etc.  Both have staves of oak, but their use of them is different in the general way I've described above.
The pictures you link are interesting.  It's hard to know what was symbolized in medieval paintings and what was not; that is to say, did the red cloak mean anything more than its color?  As for the late 1800s pictures, they reflect the Celtic strangeness that I think Tolkien didn't care for.
 
I'm not convinced that it's an issue of mysteriousness.  I think of Gandalf outside the gate of Moria and there he seems very Germanic.  So too on the Bridge of Khazad-dum.  Even more so in his first treatment of Wormtongue and Theoden.  Even the name, "stormcrow" is delightfully reminiscent of that Germanic feel.  I suppose I pretty much like the portrayal of Gandalf throughout LotR.  What I find disappointing is what one learns about him from the Silmarillion.
