Can I plate tin directly to 304 stainless?

I have an old print that requires 0.011" thick, 304 stainless, with a woods nickel flash, then electroplated with .00008 - .00024 Tin with 2% to 3% lead electroplate. Is the woods nickel flash or strike necessary? What will be the results if we don't strike?

No, you can't skip the Wood's Nickel ⇦ huh?. The result would be virtually zero adhesion. Electroplated coatings must grow on active metal, whereas stainless steel immediately passivates. The Wood's nickel is a way of simultaneously attacking/removing that passive layer while depositing a fresh nickel layer.
