Possibly. But the dscaler capture capabilities are not really supported (and only half frames), and so I have found virtualdub to be better suited to that kind of task. It allows you use different filters to clean up video, and it supports video capture using BT878 capture cards (and maybe others too). First capture the video at the highest resolution you can acheive without dropped frames (preferrably uncompressed), and then you can experiment with the filters to get the optimum results, by post processing your capture file (and then compressing, if you like). You can apply multiple filters, and download additional filters for VirtualDub. The results are unlikely to be as clean as broadcast material through Dscaler, simply because VHS is just inferior, but you can get rid of some graininess, etc. Some experimentation with settings may be necessary to get the best results.
