Daniel, and anyone else who may find this of interest.. i tried out the setup just as mentioned above, and it works!  Obviously, there are other things to take into account such as those highlighted by cerbera above, but as far as 80xx and 62xx forming a VRRP relation/group between them goes, they do it successfully.  cheers
 Hi Is it possible to run VRRP between 2 different models of PowerConnect switches. e.g. 62xx and 80xx. any advice, much appreciated.
