No, but I found your post Michael looking for a solution to the same limitation. It's such a tiny file format. The only alternative I can think of is tp drive people to LinkedIn, which is probably a little more "Modern Marketing" of us - but the .vcf file enables people to add the contact to their phones etc.
We've created shared content using a 48x48 pixel stylised icon of the LinkedIn logo and we then add this to emails or landing pages etc. Of course there's always branded "Find Me On LinkedIn" style buttons as well.
