Hi Doran,
The short answer is no … they are completely different materials that have very different properties.
There is more about how latex and memory foam compare and the pros and cons of each of them in post #2 here.
Unfortunately there are too many unknowns, variables, and personal preferences involved for anyone to be able to predict which mattress will be the best “match” for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) based on specs (either yours or a mattress) or "theory at a distance (see mattress firmness/comfort levels in post #2 here).
The risk of comfort layers that are too thick/soft for a particular person are that you may end up sleeping out of alignment. There is also more about primary or “deep” support and secondary or “surface” support and their relationship to firmness and pressure relief and the “roles” of different layers in a mattress in post #2 here and in post #4 here that may also be helpful in clarifying the difference between “support” and “pressure relief” and “feel” and why some mattresses are suitable for some people but not for others that have a different body type, sleeping position, or preferences or sensitivities.
There is more about the different ways to choose a mattress (locally or online) that can help you assess and minimize the risks involved with each of them in post #2 here but when you can’t test a mattress in person then the most reliable source of guidance is always a more detailed conversation with a knowledgeable and experienced retailer or manufacturer who can help “talk you through” the options they have available based on the information you provide them, any local testing you have done, and the “averages” of other customers that are similar to you. They will know more about “matching” their specific mattress designs to different body types, sleeping positions, and preferences and which of the firmness and layering options they have available will have the best chance of success than anyone else.
As you know the Eurotop also has the advantage of being able to exchange the firmness of the latex comfort layer so if you choose a firmness that isn’t as suitable as you hoped for then you have the option of exchanging it for a different firmness level without having to exchange or replace the entire mattress.
