Interesting question. I guess that's based on the premise that large nodes route more? Although true to a certain extent, i.e. very small nodes simply lack the liquidity to open meaningful channels, intermediate nodes are very well able to complete with large nodes, as long as they open useful channels and manage their node well. Now, at the level of the direction the lightning network goes in terms of development, nodes have nothing to say, be it large or small, except maybe in their preference of one implementation over the other. But because all implementations adhere to a global set of rules (BOLT), they are not that different in the end. So no, i don't think the size of your "stake" affects the lightning network.
