If you do not adhere to subtypes, then it is understandable why you would not think LSI is possible.

I think he is LSI2Ti (pseudo type/type mimics is ILI, Ni base), and I am IEI2Fe (pseudo ESE; Fe base).

I am proponent of subtype, because I see how you can still fit the characteristics of a type and appear like another.. I appear EIE/ESE, yet my Ti is 2d, I in no way can be a process dichotomy, the cognitive style of IEI is fitting as for me and so forth. But despite, I exhibit some Fe base quality.
