Yes you can do this as:
im1= imread('image1.jpg');
im2= imread('image2.jpg');
im3= imread('image3.jpg');
r = im1(:,:,1);
g = im2(:,:,2);
b = im3(:,:,3);
NewImage = cat(3,r,g,b);
imshow(NewImage)

I1 = imread('image1') ;
I2 = imread('image2') ;
I3 = imread('image3') ;
R = I1(:,:,1) ;
[nx,ny] = size(R) ;
G = imresize(I2(:,:,2),[nx,ny]) ; % in case if the dimensions are different
B = imresize(I3(:,:,3),[nx,ny]) ;
I = cat(3,R,G,B) ;
imshow(I)
