The 2226W tender is the only one that has a long drawbar to work with the drawbar post in the cab floor of the 226E. You could use a 2235W or 2245W by adding the 2226W long drawbar to those other smaller tenders. THey are about 3-4" to 1 inch shorter and use four wheel trucks so they will definitely look smaller behind a 226E. And btw, the prewar tinplate 6 wheel trucks that you woul dfind on a 2226W tender are just as insanely pricey as the tender which is crazy but generally the case. While I have a couple others in junky condition, I recently found this nice complete one in an antique mall in Western NY while in a business trip. It did not take me long to cave as there was a big discount on the booth at the time. So I paid a lot less than the price on the tag in the picture 
. Plus they gave a 20% discount for future purchases and I later found a set of Marklin prewar passenger cars I could not live without as well lol. Either way, if you put a smaller tender behind the 226E it won't look quite right, but it will work if you sort the drawbar situation out.
And here is the same engine after a little cleaning and service pulling all three of the cataloged passenger sets it would have pulled from 1938-1942.
