Poster design replication

I have 5 existing poster layouts (attached). I need each one replicated with only small modifications according to my specifications. It will of course not be possible to get the exact same graphical elements, so you will need to find "substitutes" for the elements, . The result will only be used/utilized internally/privately (no public display, sales or similar) I need high-res files so that the poster can be printed in approx A2 or 70x100 cm (and still look great/sharp). Specifications: The IDEA of each poster shall be kept intact. Elements, fonts, colors can be changed. But please just be as inspired by the originals as possible. We are copying the idea and design here, no need to try to hide that fact. The new posters must be toned into a matching color-palette, so that they show together and thus "feel" like they belong together. The colors that shall be used is BLUE and RED. The red color from the Icebear poster is great and should be brought forward "as is". The blue color should also the "solid dark" blue to match the red. But I foresee that a number of blue ligther shades can be used. The important thing is that the main colors is blue and red - and that the 5 posters "match" in color palette. NOT that they all have the same colors and "look alike", that would not be nice.
