Sure.  Use whatever bright tin you want.  See if you can measure the compressive stress in the deposit - like plate a coiled spring and see how much it deflects after plating -from day to day.  
 
BUT, if you use bright tin, be sure ALL tin on the component leads or circuit boards are covered by lead-containing solder.  Most important - use a stiff conformal coating OVER everything you have plated with electrolytic tin.  
 
Despite manufacturer claims, I do not believe any electrolytic tin is whisker free forever - bright or matte.  So much of tin whisker initiation depends on factors besides the tin brightner formulation that I would not trust any tin electroplate to be whisker free for 20 years.  MITIGATE, or find something besides pure electrolytic tin.

Subject: [TN] bright whisker free electrolytic Tin plating


I want to set up a Bright acid tin plating bath for reliable whisker free
tin plate of 3 to 5 microns. Any advise on the best and trouble free
chemistry?

Thanks Anil
