I think you need a kitchen designer for sure. As for removing the wall is that what you would think is an improvement ? MCM homes and galley kitchens work well together if you want to keep the styling. Could you post a floor plan . I love opening walls between the DR and the kitchen but not usually between the LR and the kitchen so think about how this would function for your life. BTW galley kitchens are awesome to work in when done right.
